Does artichoke extract help with liver health? What the research does and doesn't show

Artichoke extract's liver research is concentrated in one population: people already diagnosed with non-alcoholic fatty liver disease. There, trials found modest improvements in liver enzyme levels over a few months. No trial has tested it in people with healthy liver function, or in more serious liver disease like cirrhosis or hepatitis.

What the evidence doesn't support

It doesn't support artichoke extract as a treatment for fatty liver disease, cirrhosis or hepatitis — the positive findings are changes in blood-test liver enzymes over 8 to 12 weeks in people already diagnosed with fatty liver, not a reversal or cure of the disease itself, and no trial has included anyone with cirrhosis or hepatitis at all. It also doesn't support artichoke extract as a way to protect or improve liver function in someone with normal liver enzymes to begin with — every trial with a positive finding recruited people whose liver enzymes were already elevated.

What the trials found

A 2021 systematic review and meta-analysis pooled eight clinical trials of artichoke supplementation and liver enzymes. Across the pooled trials, AST and ALT — the two enzymes doctors use to flag liver strain — averaged lower with artichoke than placebo, an effect concentrated specifically in the non-alcoholic fatty liver disease subgroup and in overweight or obese participants. One of the trials behind that review, a placebo-controlled study of 90 adults with ultrasound-diagnosed fatty liver given 600 mg of artichoke leaf extract a day for two months, reported improved ALT, AST and liver-ultrasound findings, plus total cholesterol and triglycerides that were lower as secondary measures, with no side effects reported. A broader 2025 meta-analysis pooling trials through September 2024 found a similar pattern for ALT and alkaline phosphatase — both averaging modestly lower with artichoke than placebo — while AST showed only a borderline, non-significant change and creatinine (a kidney marker) didn't move at all. Separately, a 12-week trial in 80 adults with metabolic syndrome, not a liver-specific population, found no overall change in blood glucose, blood pressure or lipids, covered in full on does artichoke extract help with diabetes?. No trial in this literature has tested people with normal liver enzymes, and none has tested cirrhosis, viral hepatitis, or any liver disease beyond the fatty-liver studies described here.

Questions people ask

Is artichoke extract good for fatty liver?

Several small trials in people already diagnosed with non-alcoholic fatty liver disease found liver enzyme levels improved after 8 to 12 weeks, most consistently at 600 mg a day. That's evidence about a specific, diagnosed condition under medical monitoring — not a basis for using artichoke extract to self-treat suspected liver problems instead of seeing a doctor.

Does artichoke extract help detox the liver?

"Detox" isn't a measured outcome in any of these trials — they tracked specific liver enzymes and imaging findings in a diagnosed population, not a general detox effect. See does artichoke extract help with detox and cleanse? for that question directly.

How does artichoke extract help the liver?

In the trials that found an effect, artichoke leaf extract was linked to lower ALT and AST enzyme readings over 8 to 12 weeks in people already diagnosed with fatty liver disease — a lab-marker change measured in trials, not a mechanism established in a broader population.

When to talk to a doctor

Fatty liver disease, and any other liver condition, is diagnosed and monitored by a doctor with blood work and imaging — artichoke extract is not a treatment for it. If you have a diagnosed liver condition or take medication that affects the liver, talk to a doctor before adding a supplement, and don't use one instead of the monitoring or treatment a doctor recommends; see artichoke extract and medications: what to check.
